DWRB101 (DWR28 / BH581) is a new malt barley variety, which was developed using pedigree method at DWR, Karnal. The variety was identified for irrigated timely sown conditions of North Western Plains Zone (NWPZ) during 53rd All India Coordinated Wheat and Barley Worker’s Meet held at JNKVV, Jabalpurduring 22-25 Aug. 2014.

DWRB101 was tested at a total of 31 locations with four checksviz. DWRUB52 and DWRB92 (both two-row type) and K 551 and BH 902 (both six-row type) under coordinated evaluation trials.

DWRB101 is erect type in growth habit with mean maturity of about 132 days and having average plant height of 97 cm. Spikes are erect, tapering type in shape with rudimentary lateral florets.

Grains are bold with medium hard texture, oblong shaped and yellow in colour with 46.9g 1000 grain weight. A comparison of DWRB101 with check varieties for ancillary traits is given in Table 1.

DWRB-101 is having resistance to yellow rust under field conditions (natural scores=0) and also has specific advantage over recent malt barley check DWRB92 under artificial inoculations. DWRB101 also showed better resistance to leaf blight over all the checks under field conditions with double digit scores of 13 (2012-13) and 12 (2013-14), respectively.
